This afternoon I got a notification on stock Droid X "insert sdcard". I checked Astro file manager and it said sd card was blank, and asked if I wanted to format sdcard. I said no. I hooked phone up to computer and computer wouldn't recognize phone as mass storage device. I pulled sdcard from phone and inserted into computer micro sdcard adapter. Computer still would not read sdcard. I pulled sd card from my Droid1, and first checked it on the computer. It read original droid sdcard fine. I inserted the Droid1 sdcard into my DroidX and it recognized the original Droid card. Droid X automatically updated a few of my programs (only had Droid X since Christmas), and everything now appears to be working fine. WHAT happened?
